Segmented magnet homopolar dynamoelectric machines having
fluid cooled liquid metal current collecting zones

ABSTRACT

A HOMOPOLAR DYNAMOELECTRIC MACHINE IS CONSTRUCTED WITH A MAGNETIC FIELD THAT IS BROKEN INTO SEGMENTS ALONG THE AXIS OF THE MACHINE. LIQUID METAL CONTACTS ARE UNTILIZED TO TRANSMIT ELECTRICAL ENERGY BETWEEN THE ARMATURE AND CURRENT COLLECTING MEMBERS WHICH HAVE DUCTS FOR THE TRANSMISSION OF COOLING FLUID LOCATED THEREIN. GROUPING ARMATURE CONDUCTORS, AND APPROPRIATELY INTERCONNECTING THE CURRENT COLLECTING MEMBERS TO SERIALLY RELATE THE VOLTAGES INDUCED IN THE ARMATURE CONDUCTORS IN ORDER TO INCREASE THE MAGNITUDE OF THE OUTPUT VOLTAGE, PERMITS ACHIEVEMENT OF THE DESIRED OUTPUT CHARACTERISTICS.

Int. Cl. H02k 31/00 US. Cl. 310-178 2 Sheets Drawing. 15 Pages Specification A homopolar dynamoelectric machine is constructed with a magnetic field that is broken into segments along the axis of the machine. Liquid metal contacts are utilized to transmit electrical energy between the armature and current collecting members which have ducts for the transmission of cooling fluid located therein. Grouping armature conductors, and appropriately interconnecting the current collecting members to serially relate the voltages induced in the armature conductors in order to increase the magnitude of the output voltage, permits achievement of the desired output characteristics.
